To solve this problem, we need to follow the order of operations, often remembered by the acronym BODMAS/PEMDAS. This means we perform operations in the following order: Brackets/Parentheses, Orders/Exponents, Division and Multiplication (from left to right), and Addition and Subtraction (from left to right).
The value of the expression is 62.
C) 62 — This is the correct result obtained by following the BODMAS rule.
The question asks for the primary industrial process for producing phenol globally and the key intermediate involved. We need to identify the most prevalent method and its characteristic intermediate.
Therefore, the Cumene process uses cumene hydroperoxide as the intermediate.
Correct Option: C) Cumene process, cumene hydroperoxide. This is the most widely used industrial method for phenol production, and cumene hydroperoxide is the crucial intermediate formed by the oxidation of cumene.
The question asks to identify the specific Gumpha (cave) at Khandagiri, Odisha, that is renowned for carvings depicting the twenty-four Jain Tirthankaras. This requires knowledge of the prominent features of the caves at Khandagiri and Udayagiri.
A) Trusula Gumpha — Trusula Gumpha (also spelled Trishula Gumpha) at Khandagiri is well-known for its intricate carvings, which include depictions of the twenty-four Jain Tirthankaras. These carvings are significant for understanding the early iconography of Jainism in the region.
This problem involves substituting given symbols with mathematical operators and then evaluating the resulting expression using the BODMAS/PEMDAS rule (Brackets, Orders/Exponents, Division, Multiplication, Addition, Subtraction).
First, let's list the given symbol-operator mappings:
We need to evaluate each option by replacing the symbols with their corresponding operators and then performing the calculations in the correct order.
Let's evaluate option C: 32 P 8 S 30 R 16 Q 4
Since the result is 38, option C is the correct answer.
To find the value of \(k\) for which a quadratic equation has equal real roots, we need to use the discriminant property. For a quadratic equation of the form \(ax^2 + bx + c = 0\), the discriminant is given by \(\Delta = b^2 - 4ac\). For equal real roots, the discriminant must be equal to zero.
Thus, the value of \(k\) for which the equation has equal real roots is 9.
C) 9 — When \(k=9\), the discriminant \(b^2 - 4ac = (-6)^2 - 4(1)(9) = 36 - 36 = 0\), which means the equation has equal real roots.
To solve this problem, we need to first identify all the digits present in the given number. Then, we will arrange these digits in ascending order. Finally, we will pick the digit that is third from the left in the newly arranged sequence.
Therefore, the digit third from the left is 3.
D) 3 is the correct answer because after arranging the digits of 4917523 in ascending order (1, 2, 3, 4, 5, 7, 9), the third digit from the left is 3.
The question asks for a feature in MS-PowerPoint 2019 that allows reusing slides from another presentation without manual copying. We need to identify the specific feature designed for this purpose.
C) Reuse Slides (under the Home tab)
The "Reuse Slides" feature in MS-PowerPoint 2019 (found under the Home tab in the Slides group) is specifically designed to insert slides from another existing presentation into the current one. This allows users to browse for a presentation file and then select individual slides or all slides to add to their current presentation, maintaining their original formatting or adopting the new presentation's theme.
The problem presents a series of three-letter codes. We need to identify the pattern in the letters of each code based on their positions in the English alphabet and then apply that pattern to find the missing code.
Let's analyze the given series: XCH, RWB, LQV, FKP, ?
We will examine the pattern for each position (first, second, and third) of the letters in the codes.
Combining the next letters for each position, we get Z, E, J.
Therefore, the missing term is ZEJ.
B) ZEJ is the correct option as it follows the established pattern of decreasing by 6 for each corresponding letter in the sequence.
The problem requires us to evaluate a mathematical expression after interchanging specific arithmetic operators. We need to replace '+' with '−' and '−' with '+', and '×' with '÷' and '÷' with '×'. After performing these interchanges, we will solve the new expression following the order of operations (BODMAS/PEMDAS).
Correct Option: A) 855
